What are some common mistakes to avoid when transitioning from a custom autoloader function to Composer's autoload functionality in PHP?

One common mistake to avoid when transitioning from a custom autoloader function to Composer's autoload functionality in PHP is forgetting to update the namespaces in your classes. Make sure to update the namespaces to match the PSR-4 standard used by Composer. Additionally, ensure that your Composer autoload configuration is correctly set up in the composer.json file. 

// Before transitioning to Composer's autoload functionality
function custom_autoloader($class) {
    // custom autoloader logic
}

spl_autoload_register('custom_autoloader');

// After transitioning to Composer's autoload functionality
// Update the namespaces in your classes to match PSR-4 standard
// Ensure that Composer autoload configuration is correctly set up in composer.json
